What We Check
Sitemap type, URL count, child sitemap count, duplicate URLs, homepage presence, and a sample of sitemap URLs for status issues.
Why It Matters
A sitemap can exist and still be weak. Duplicate entries, missing homepage coverage, or stale broken URLs reduce sitemap trust.
Best Follow-Up
After validating the sitemap itself, run the sitemap audit to inspect the listed pages for broader technical SEO issues.
What is a sitemap validator?
A sitemap validator checks whether the sitemap file you publish is structurally sound and useful to search engines. It confirms that the file can be fetched, that the XML is valid, that the sitemap type is correct, and that the URL set does not contain obvious quality issues like duplicates or broken pages.
This matters because a sitemap is not just a list of URLs. It is a trust signal. If the file repeatedly contains redirected, non-canonical, broken, or stale URLs, search engines treat it as less reliable for discovery and recrawling.
How this sitemap validator works
1. Discover the sitemap
The tool finds the declared or expected sitemap location before validating the file contents.
2. Parse the XML
It confirms whether the file is a regular sitemap or sitemap index and counts the URLs or child sitemaps it contains.
3. Check for quality issues
Warnings are generated for duplicate URLs, missing homepage coverage, invalid structures, and sampled URLs that fail basic status checks.
4. Publish a shareable report
The result gets a public report URL so the sitemap state can be shared, rechecked, and tracked after fixes are deployed.
Common sitemap mistakes this tool catches
Redirects and dead URLs in the sitemap
A sitemap should point to canonical 200 pages. Redirects and broken URLs reduce the trustworthiness of the file.
Duplicate entries
Duplicate URLs often indicate generation bugs, overlapping child sitemaps, or inconsistent canonicalization at the CMS level.
Missing homepage coverage
When the homepage is absent from the sitemap, it is often a sign that the sitemap generation logic is incomplete or fragmented.
Confusing sitemap index structures
Large sites often rely on sitemap indexes. If the child files are malformed or stale, discovery can degrade even when the root file exists.
Frequently asked questions
What does this sitemap validator check?
This tool discovers the sitemap, confirms the file type, counts child sitemaps and URLs, flags duplicates, checks homepage inclusion, and samples sitemap URLs for response issues.
Why validate a sitemap if it already exists?
A sitemap can exist and still be weak. Invalid XML, duplicate URLs, redirected entries, or missing key pages reduce its value as a discovery signal.
Does this replace a full sitemap audit?
No. This validator checks the file itself. The sitemap audit goes wider and checks the listed URLs for page-level technical issues.

The sitemap validator checks the file itself. Use the sitemap audit for multi-page SEO checks, the robots.txt checker to confirm crawl access, or the meta tag checker when you want to QA one important page in detail.
